can somebody help me to modify following chinese rice bulb circuit to have 1w LED s or 100w fillement bulbs. if i can modify this to have a more powerful thyrister i will be able to power 100w bulbs for wesak lanterns .
i tried adding 1w LED using a capacitor but it worked once and stopped. i think the output thyristors are gone.

Thank you in advance.

 

If you want to modify the circuit then you should draw the circuit first, the circuit was not that much, so draw it and upload it as 800x600 .gif or .jpg file.

 

How do you know they are thyristors, there is a module on a pcb probably provides the gate signals, and what voltage are you using?

 

Thank you for your replies guys. This is the circuit

Pcr 406 is a thyristor is not it ??

If you still want to ask that it means that your knowledge is not enough to do the circuit, if you want to using bulb then maybe you can google : triac dimmer and if you have any problem about triac circuit then you still can post it, but you just be careful the safety issue.
